Wavefront-guided refractive surgery results of training-surgeons.

Purpose: To assess clinical outcomes and changes on higher-order aberrations (HOA) after wavefront-guided laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for correction of myopia and myopic astigmatism performed by training-surgeons.

Methods: One hundred and seventy patients had customized LASIK (207 eyes) and PRK (103 eyes) performed by surgeons in-training using the LADARVision 4000 (Alcon, Fort Worth, TX). Preoperative and 1, 3, 6 and 12 months postoperative data of spherical equivalent (SE), best spectacle-corrected visual acuity (BSCVA) and uncorrected visual acuity (UCVA) were analysed.

Long-term follow-up of orthokeratology corneal reshaping using wavefront aberrometry and contrast sensitivity.

Purpose: To evaluate changes in ocular wavefront aberrations and contrast sensitivity during 1-year follow-up of overnight orthokeratology.

Methods: Prospective study of 26 eyes that underwent orthokeratology with the BE lens design. Wavefront measurements were analyzed at baseline and after 1, 8, 30, 90, 180, and 365 nights of orthokeratology for a 6.

Long-term results of photorefractive keratectomy for myopia and myopic astigmatism.

Purpose: To assess the long-term refractive outcomes of photorefractive keratectomy in myopia and myopic astigmatism.

Methods: A retrospective study of 120 photorefractive keratectomy operated eyes with at least four-year follow-up (maximum of 96 months, mean follow-up 55 months). We divided patients into group 1 (G1) spherical equivalent (SE) up to -4.

Stability of wavefront aberrations during the daytime after 6 months of overnight orthokeratology corneal reshaping.

Purpose: To evaluate the stability of wavefront aberrations during the daytime after 6 months of overnight orthokeratology corneal reshaping.

Methods: A prospective study of 26 eyes using the Ultravision BE lens design during 6 months of overnight wear. Uncorrected visual acuity (UCVA), cycloplegic refraction, and wavefront aberrometry were measured at 8 AM (within 1 hour after awakening and removing lenses), 1 PM (5 to 6 hours after lens removal), and 6 PM (10 to 12 hours after lens removal).

Bubble and corneal dimple formation after the first overnight wear of an orthokeratology lens: a case series.

Purpose: To report the first documented case series of bubbles and corneal dimples associated with corneal reshaping after the first overnight wear of an orthokeratology lens.

Methods: Three cases of transient corneal dimples are described after the first overnight use of the Be Free orthokeratology lens (BE; Ultravision Pty. Ltd.

Corneal changes and wavefront analysis after orthokeratology fitting test.

Purpose: To evaluate corneal changes and ocular aberrations during an orthokeratology test.

Design: A prospective, nonrandomized cohort study.

Methods: Fourteen myopic patients (26 eyes) underwent an orthokeratology fitting test with the BE contact lens (Ultravision Pty, Ltd, Brisbane, Australia).

[Economic impact of eyedrop cost in glaucoma treatment].

Purpose: To evaluate the daily cost of antiglaucoma eyedrops and the economic impact related to the minimal wage; to compare the cost of drug association in the single presentation in relation to separate presentations; to analyze the additional percent antiglaucoma drug cost related to standard therapy (generic timolol maleate).

Methods: Fifteen eyedrop bottles of each one of the twenty antiglaucoma products were used. The number and mean eyedrop size per bottle of drug were measured and the duration and treatment costs calculated.
